I use oil 10w40 and when I measured engine compression I measured 160psi. If the compression is low means the car (engine) burning oil because of the problem with the rings.
My car burning oil and I use oil 10w40, looks like I have a problem with the rings.

I wouldn't worry much about there being *only* 160 PSI being indicated. Make sure you check all the cylinders.

The reason I say not to worry about it is because there isn't much you can do about it, shy of tearing the engine down and rebuilding it.

Some compression gauges are a piece of crap, and "low" compression is not necessarily an indicator of an engine's health. If it runs good, doesn't consume much oil, and gets decent fuel economy, then just run it.

Compression figures are also not definitively indicative of how much oil it will consume. Sometimes they go hand in hand, sometimes not. My old Geo Metro was making a pretty normal 175 PSI on all three cylinders, yet went through a quart of oil in 500 miles.

My engine spends around 1.5 - 2 liter for 3,000 miles. Engine compression 160 psi is a little bit for me because the new car has 200 psi (reading manual). I would accept up to 170 psi.
In my case, it's time to change the engine rings.

I wouldn't worry much about there being *only* 160 PSI being indicated.......etc.

I agree.....
10:1 compression ratio means (14.7 psia (sea level) x 10)-1 = 132 psig at constant temperature (isothermic) but rapid compression causes temperature increase, tends toward adiabatic..hence a higher pressure is expected...but it depends on engine temperature, if compression is rapid, etc...so the exact value can vary.....
FOr me....adding some oil from time to time....ehhh....extends the oil change interval ....
But..brian, ..if you are in the mood for an adventure.....that is your choice, period. BUt keep us informed
